|Abstract:||This work aims to a better understanding of augmentation network security. In more details, the objective is to simulate a spoofing attack aimed at introducing displacements in the positions computed by rovers that make use of an augmentation service. At first, we investigated the features of such an attack. Then, after introducing the Local Area Augmentation System presented in , we evaluated its vulnerabilities. At this aim we generalized the methodology introduced in  in order to evaluate the effects on the rovers of faults affecting the Reference Stations employed by the Augmentation Network to the case in which the errors affecting the pseudoranges, measured by different stations, are correlated, as in case of coordinated spoofing. The analytical evaluation is complemented by numerical results obtained by a GNSS simulator, fed with data recorded by a reference station network deployed in the Sardinia Island (Italy), in order to assess the feasibility of a train control system integrating GNSS technologies.|
